DRILL STEEL RETAINER 2 Sheets-Sheet l Original Filed May ,16, 1925 A. H.SKAER DRILL STEEL RETAINER 2 Sheets-Sheet 2 9 9 L 2 a M Original FiledMay 16, 1925 A-fifian' I awozmq steel andhas an orifice through whichthesteel passes,,a part of this orifice being suf ficiently small toprevent the passage of the collar and a portion sufficiently large topermit the passage of said collar, and a link pivo'tally connected tothe retaining'link and pivotally mounted on the steel holding means topermit the retaining link to be positioned so that the steel'will passthrough either of said portions ofthe orifice.

3. The combination with means for bolding a collared drill steel, of aretainer for the steel comprising a link thatvsurrounds the steel andhas an orifice through which the steel passes, a part of'this orificebeing sufficiently small to prevent the passage of the,

collar and a portion sufliciently large to permit thepassage, of saidcollar, and-a llnk pivotally connected to the retaining link at thebroader side of the orifice, said link being pivotally mounted on thesteel holding means to permit the retaining link to be positioned sothat the steel will pass through either of saidportions of the orifice.

4. .Thecombination with means for bolding a collared steel and having asocket for receiving such steel, of a retaining link comprisingangularly disposed portions, one portion having its interior space ofless width than the collar of the steel, the other portion having itsinterior space greater than the width of said collar, and a pivotalmounting for the retaining link engaged with y the outer free end of oneof said angular por tions, said mounting being of a lengthLto I permiteither portion to swing to a position across the drill steel in advanceof the holding means.

5. The combination with means for holding a collared steel and having asocket torreceiving such steel, of a retaining link comprising angularlydisposed portions, oneportion having its interior space of less widththan the collar of the steel, the other portion having its interiorspace greater than the width of said collar, a ring mounted on the steelholding means, and a link pivoted to the ring and to the retaining link.

6. The combination with means for holding I a collared steel and havinga socket for receiving such steel of a retaining link comprisingangular-1y disposed portions, one portion having its interior space ofless width than the collar of the steel, the other portion having itsinterior space greater than the width of said collar, a ring mounted onthe steel holding means, and a link pivoted to the ring and to the outerend of the portion of the link having the larger interior space.

7. The combination with a drilling motor having means for holding acollared steel to V be operated on, of a retainer for the steelcomprising a link that surrounds the steel in advance of the collar andhas angularly disposed portions, and a flexible connection between thelink and the drilling motor for securing the link to themotor wholly inad- Vance of the retaining means and permitting either of the angularportions of the link to be moved to a position across the steel inadvance of the holding means and with the steel extending therethrough.

8. They combination with aholder that detachably'receives a collaredsteel, of a retainer forsaid steel comprising a link having a portionthat will permit the passage of the collar of the steel and an angularlydisposed smaller portion that will prevent the passage of the collar,and means at. one side of the holder and steel for mounting the link topermit its smaller portion to embrace a steel transversely thereof andin advance of the collar thereof and in advance of the holder and alsopermit the angularly disposed larger portion to be positionedtransversely of thesteehcompletely across the same and in advance of theholder to permit the passage of the collar of the steel therethrough.

9. The combination with a holder that detachably receives a collaredsteel, of a retainer for said s'teelcomprising a link: having a portionthat will permit the passage of the collar of the steel and a smallerportion that will prevent the passage of the collar, and means at oneside of the holder and-steel for loosely hanging the link by its largerpor-, tion at one side of the holder and in a position to permiteitherits larger or smaller portion to swing to a position transversely of thesteel completely across the same and in advance of the front endjof theholder toprevent or permit the passage of the collar of a drill steeltherethrough.

10. The combination with a, holder that detachably receives a collaredsteel, of a retainer for said steel comprising a link having angularlydisposed portions of different internal cross sectional areas, thesmaller portion. preventing the passage of a steel collar therethrough,the larger portion permitting such passage, and meansat one sideof. theholder and steel for loosely hanging the link at one side oftheholderand in a posi- 'dng'ularly' dis posed qporitions of differenttiOn" tonormally 'embra ce the steel? transportioii 'preventingithe"passage of "a; st eel but: permit-ting the largepportion to be m.,qcollzir therethroughfthe larger portion perswung transversely and"completely "across I 15 mittin g such ,passageffand means at one side ftheteel and in advancgof theiront flend of thalinkby; its'largelfportion at on eside' 0f In witnesswhreof I aQflix mysignature,the holder and steelim cause the-smaller 13gb -ARTHUR SKAER.
